【摘要】：我國大多數(shù)空調系統(tǒng)處于靜態(tài)設計、病態(tài)運行和粗放的管理維護的狀態(tài)中,致使我國空調系統(tǒng)能耗占據(jù)了整個建筑能耗很高的比例,空調系統(tǒng)能耗巨大的問題成為我國城市的一個重要的和棘手的問題。因此空調系統(tǒng)的合理設計、優(yōu)化運行和高效管理對于城市的能源管理是非常關鍵的。在空調系統(tǒng)的運行階段,空調系統(tǒng)的能耗診斷實用研究對于減少現(xiàn)有空調系統(tǒng)的能耗和提高能源使用率起著非常重要的作用。本文從最基本的空調系統(tǒng)Commissioning方法出發(fā),主要對空調系統(tǒng)的能耗診斷具體理念和實用過程方法進行研究。采用建筑能耗模擬手段與組態(tài)軟件監(jiān)控手段相結合對一般的空調系統(tǒng)進行能耗診斷。對于最優(yōu)狀態(tài)下建筑內空調系統(tǒng)運行能耗采用軟件模擬和理論計算的手段,運用正交試驗的方法針對同一建筑冷負荷下不同空調系統(tǒng)各個節(jié)點不同運行參數(shù)組合進行方案研究,探尋出滿足空調區(qū)室內設計參數(shù)并且能耗最低的最優(yōu)的空調系統(tǒng)運行狀態(tài)的方案。對于實際狀態(tài)下空調系統(tǒng)能耗運用監(jiān)控軟件進行監(jiān)控和數(shù)據(jù)采集,再對數(shù)據(jù)做一些合理處理。分項計量空調系統(tǒng)的每一個壓縮機、水泵和風機等耗電設備的電功率是關鍵過程。在這個過程中,首要任務是診斷和驗證系統(tǒng)的運行性能(實際狀態(tài)),得到充足的偏離“理想”和“最優(yōu)”運行狀態(tài)的信息。系統(tǒng)的機組壓縮機、水泵和風機電功率(實際能耗)分別單獨計量。并且,最優(yōu)狀態(tài)下運行的數(shù)據(jù)可以通過模擬或計算得到,實際狀態(tài)下的能耗數(shù)據(jù)通過組態(tài)監(jiān)控軟件進行收集。這兩種數(shù)據(jù)可以通過能耗偏離度的概念分析,從而對空調系統(tǒng)進行能耗診斷。
[Abstract]:Most air conditioning systems in our country are in the state of static design, sick operation and extensive management and maintenance, which results in a high proportion of energy consumption in the whole building.The problem of huge energy consumption in air-conditioning system has become an important and difficult problem in Chinese cities.Therefore, the rational design, optimal operation and efficient management of air-conditioning system are very important for urban energy management.In the operation stage of air conditioning system, the practical research on energy consumption diagnosis of air conditioning system plays a very important role in reducing the energy consumption of the existing air conditioning system and improving the energy utilization rate.Starting from the most basic Commissioning method of air conditioning system, this paper mainly studies the concrete idea and practical process method of energy consumption diagnosis of air conditioning system.The energy consumption diagnosis of general air conditioning system is carried out by means of building energy consumption simulation and configuration software monitoring.Under the optimal condition, the operation energy consumption of air conditioning system in buildings is simulated by software and calculated theoretically, and the orthogonal test method is used to study the scheme of different nodes and different operation parameters combination of different air conditioning system under the same building cooling load.The optimal operation state of air conditioning system which meets the indoor design parameters and has the lowest energy consumption is explored.The monitoring software is used to monitor and collect the actual energy consumption of air conditioning system, and the data is processed reasonably.The key process is to measure the electrical power of every compressor, pump and fan in the air conditioning system.In this process, the primary task is to diagnose and verify the performance of the system (actual state), and obtain sufficient information deviating from the "ideal" and "optimal" running state.The unit compressor, water pump and fan electric power (actual energy consumption) of the system are measured separately.Moreover, the data in the optimal state can be obtained by simulation or calculation, and the energy consumption data in the actual state can be collected by the configuration monitoring software.The two kinds of data can be used to diagnose the energy consumption of air conditioning system through the conceptual analysis of the deviation of energy consumption.
